AUTOMATIC LIQUID-DISPENSING DEVICE.

an apparatus which may be actuated to automatically deliver a measured quantity of liquid, as for instance beer.

Another object is to provide such an apparatus which may be adjusted to deliver ditlerent quantities of liquid.

7 Other objects are to simplify the construction of such apparatus and provide an apparatus efi'icient and reliable in operation. With these ob ects in view the invention comprises generally a dispensing nozzle or faucet provided with a normally closed stop-cock, retaining ineaii's for retaining said stop-cock in open position during passage of liquid, releasing means, and .i'neans actuated by the flow oi liquid actuating said releasing nae-ans upon passage of a pre determined quantity of liquid.

The invention will he described more in I detail in connection with the accompanying dii'awin s illustratin on a :5 thereof, whereinl W i 1 11- f tkn 1 0 L lguie 15 an eeiauon o it app.1ra. i with cover removed) showing one side thereof. l lg. 2- 1s avertical sec nal view of the apparatus. l 1g. 3 1s a. horizontal secembodiment tional view on line 3-3 Fig. 1, Fig. 4. is a horizontal Fig. 2. p

In the drawings 5 designates the dispensing nozzle having a passage 6 therethrough for the How of liquid. In" the upper part or" said nozzle and adapted to close the passage 6 is any suitable stop coclc or valve 7. shown the stop-cock 7 in the'form of a slide or gate valve reciprocating in a here 8 at right angles to passage 6 and abutting against a seat 9 formed in said passage. When in closed position the valve 7 corn pletely shuts off the flow of liquid. Stopooelt 7 is actuated by a lever 1 pivotally mounted upon a pin 11 projecting from a lug 3 formed uphn the device. Lever 10 is provided with an arm 13 engaging within a sectional view on line H specification of Letters Patent Patented Dal-58. 3 1912 Application filed. August 26, 1910.

slot 14 in the valve 7.' The stop-cock 7 is normally retained in closed position bya springlo, reacting against a fixed part of the structure and a projection 16 upon lever l0.- The spring, when in the form of a coiled spring, as shown, is preferably braced by a pin 17 projecting through its coils. The pin 1? may pass through the projection 16 at one end and be attached to a, fixed part of the structure at its other end.

In order to hold the stopcock open, lever 10 is provided with a detent 18, pivoted thereto at 18. lhe detent 18 is provided with a pin or stud 19, which is adapted to be engaged by a projection 20 in a fixed part oi the s ructure. Projection 20 has a cam surl'ace 21 on its upper side. hen lever 10 is depressed to withdraw the stopcock 7 to open position, detent 18 is moved :iorward, its pin 19 riding upon cam suriu e 2.1 of projection 20. When, the parts reach their fully open position pin 19 drops down behind projection 20 and is retained, thus holding the parts in open position. The passage! 6 now being open liquid is free chan'iber preferably intersectii'ig passage (3. This chamber is closed on its open side by asnug-litting cap or plu 22'. In this iihan'iber is mounted wheel :23 adapted to be rotated by the flow of liquid. This Wheel preferably has a plurality of measuring buckets around its circumference, by which measured quantities of. liquid are passed as it rotates. The wheel is keyed to a shaft 25, passing through one side of (Zllfill'llXiI' 22h) the exterior. On the end of shaft :25 is an eccentric pin 26 or equivalent device. The eccentric pin 26 engages one end of an arm 27, pivoted'at 28 to a fixed part of the structure. A slot 28 is preferably formed in the arm for engagement of the pin. Arm 27 has pivoted thereto a weighted pawl 2.) having a tooth 30 engagin;- the teeth 31 of a toothed wheel 32 pivoted in any suitable manner upon the structure, as for instance upon the. reduced portion of a. lug 33 projecting from the device. A weighted pawl 34 having a teeth 35 also engages wheel 32 for the purpose of preventing hack motion of the wheel when actuated by pawl 29. Pawl 34. is preferably pivoted to a lug 36 projecting from the device. The tail of this pawl also overhangs the tooth 30 on pawl 29 so as to be lifted when pawl 29 is liited out of engagement predetermined amount of liquid has passed,

pin 37 on wheel 32 comes in contact with the cam surface 38 on detent 18, thus gradually raising the detent. \Vhen pin 19 on detent 18 is raised above the edge of projection 20 spring 15 is free to act, and retracts the detent and forces stop-cock 7 forward to close the passage 6 and thereby cut oil the flow of liquid. Detent 18 is provided with an arm 40; which, when the detent is raised by pin 37 on wheel 32, comes in contact with the tail of pawl 29 and lifts it, together with pawl 34, out of engagementwith the teeth of wheel 32. Wheel 32 is returned to initial position by any suitable means. As shown, the wheel is weighted at one side, as at 41. Substantially all of the liquid passing through the device is measured thereby, in-

asmuch as the raising and dropping of the detent behind its stop (and consequent release of the ratchet wheel) in the opening operation, is momentary, and the initial return of the ratchet wheel is sluggish, the latter being substantially in equilibrium. Consequently when the detent lifts the actuating stop pawl from the ratchet wheel, the latter has not acquired suflicient potential force or unstability to return it materially before the pawls again drop into engagement with the ratchet wheel.

In order to provide for the adjustment of the apparatus to deliver different quantities of liquid, there is provided an adjustable stop 42. As shown, this stop works in a slot 43 in the casing and is fixed in position by a screw or screws 44. This stop engages with a pin or projection 45 on wheel 32. By

lowering the stop the initial position of the wheehand consequently pin 37, is advanced,

' so that wheel 32 will have to rotate a less distance before pin 37 comes in contact with and releases detent 18 to shut off the flow of liquid. The quantity of liquid may be varied by these means either minutely or over a wide range.

. A deflector 46 is preferably formed in passage 6 adjacent to chamber 22 to direct liquid upon the tips of buckets 24, in order to give the wheel 23 a more positive action.
